Simpson was airlifted by helicopter to Houston’s Memorial Hermann Medical Center, experiencing all the symptoms of a massive heart attack.

But an angiogram revealed there was no heart attack. Doctors instead diagnosed her as suffering “takotsubo cardiomyopathy,” which is more commonly known as broken heart syndrome.

“[There is] no way to tell broken heart syndrome from a heart attack,” her cardiologist, Dr. Shezhad Sami, said.

Simpson’s incident occurred last year and was recently brought to light in the New England Journal of Medicine which said takotsubo cardiomyopathy "typically... occurs in post-menopausal women preceded by extreme stress or an emotional event."
